Income & Coverage Information

Existing coverage includes employer long-term disability (LTD), SSDI, or any individual disability policy you already pay for. The standard income replacement target is 60% of your pre-tax monthly income.

Disability Insurance Examples

Example 1: No Existing Coverage

Profile: $5,000/month income, no existing disability coverage

Calculation: $5,000 × 60% − $0 = $3,000

Monthly Coverage Needed: $3,000/month — Annual Premium Estimate at 1%: $360/year

Example 2: With Employer LTD Coverage

Profile: $5,000/month income, $1,000/month existing employer LTD coverage

Calculation: $5,000 × 60% − $1,000 = $2,000

Monthly Coverage Needed: $2,000/month — Annual Premium Estimate at 1%: $240/year

Example 3: Higher Income Earner

Profile: $6,000/month income at the 60% standard, no existing coverage

Calculation: $6,000 × 60% − $0 = $3,600

Monthly Coverage Needed: $3,600/month — Annual Premium Estimate at 1%: $432/year

The Formula Behind the Calculator

Disability Insurance Formulas
Monthly Coverage Needed = Monthly Income × 60% − Existing Monthly Coverage
Annual Premium Estimate = Monthly Coverage × 12 × Premium Rate

Monthly Income = Your current gross (pre-tax) monthly income

60% = Standard income replacement target used by most advisors

Existing Monthly Coverage = Employer LTD, SSDI, or other disability benefits (subtracted)

Premium Rate = Typically 0.5%–2% of annual income (default 1%)

How to Use This Calculator

Enter Your Monthly Income

Provide your gross monthly income before taxes. The calculator applies the standard 60% income replacement target, which is designed to replace the portion of your paycheck you actually take home and spend.

Subtract Existing Coverage

Enter any disability benefits you already have, such as employer long-term disability insurance, Social Security Disability Insurance (SSDI), or an individual policy. These are subtracted so you don't over-insure and overpay.

Estimate Your Premium

Choose a premium rate between 0.5% and 2% of your annual income. The default 1% is typical for a healthy professional. Your actual rate depends on age, health, occupation class, elimination period, and benefit duration.

Understanding the 60% Rule

The 60% income replacement target works because disability benefits are often paid with after-tax dollars or tax-free premiums, and your work-related expenses disappear when you stop working. Here's how different factors affect your numbers:

🟢
Tax-Free Premiums
If you pay premiums with after-tax dollars, your benefits are tax-free — 60% coverage goes further than it appears.
🟡
Employer-Paid Premiums
Employer-paid LTD premiums make benefits taxable. You may need a higher replacement percentage to net the same amount.
🔴
Employer Caps
Employer LTD often covers 60% but caps at $5,000–$10,000/month. High earners typically need an individual policy on top.
📊
Elimination Period
Choosing a longer elimination period (90 vs 30 days) can lower your premium by 20–30% or more.

How Much Disability Insurance Do You Really Need?

Your income is your most valuable asset — for most people, it's worth more than their home, car, and investments combined. Yet disability insurance is one of the most overlooked forms of financial protection. The Social Security Administration estimates that more than 1 in 4 of today's 20-year-olds will become disabled before reaching age 67, and a disability lasting three months or longer is far more common than most people realize.

The widely accepted standard is to replace about 60% of your pre-tax monthly income. This target works because your disability benefits replace the income you actually spend, not the portion withheld for taxes and work-related costs. If your disability insurance premiums are paid with after-tax dollars, your benefits are tax-free, making 60% coverage feel like closer to 75–80% of your take-home pay.

Start with the 60% rule, then subtract any coverage you already have — employer long-term disability, Social Security Disability Insurance, or personal policies. The result is the gap you need to fill with an individual disability policy. Review this number whenever your income changes significantly, since coverage that was adequate at $5,000/month may leave you short at $8,000/month.

Understanding Key Disability Insurance Terms

Own-occupation vs. any-occupation. An own-occupation policy pays benefits if you cannot perform the duties of your specific occupation, even if you could work in another field. An any-occupation policy only pays if you cannot work in any occupation for which you're reasonably suited by education and training. Own-occupation is significantly more protective — and more expensive — and is especially important for surgeons, attorneys, and other specialized professionals.

Elimination period. This is your waiting period before benefits begin — commonly 30, 60, or 90 days. A longer elimination period lowers your premium because you bear more of the initial risk, so it's a key lever for fitting disability coverage into your budget. Just be sure you have enough emergency savings to cover the gap.

SSDI waiting period. Social Security Disability Insurance has its own 5-month waiting period before benefits start, and you must be disabled for at least 12 months or expected to die to qualify. After 24 months of SSDI benefits, you become eligible for Medicare. Private disability insurance and SSDI can work together, but SSDI approval is difficult and can take months or years — never rely on it as your only protection.

Employer LTD vs. Individual Disability Insurance

Many workers assume their employer-provided long-term disability insurance is enough, but employer LTD policies typically cover only about 60% of base salary and are subject to caps — often $5,000 to $10,000 per month. That means high earners can face a significant coverage gap. Employer LTD also usually ends when you leave or lose your job, and group policies are not portable.

An individual disability policy is owned by you, stays with you between jobs, and can be tailored with riders like cost-of-living adjustments, residual benefits for partial disability, and future purchase options that let you increase coverage as your income grows. A common strategy is to layer individual coverage on top of your employer policy to close the gap between 60% of income and the employer's cap — exactly what this calculator helps you identify.

Also consider the benefit duration. Employer policies often pay for only 2 to 5 years or until age 65. If your savings and other assets can't carry you through a long-term disability, look for a policy with benefits to age 65 or longer, and keep the elimination period as long as your emergency fund can comfortably support.

Frequently Asked Questions (FAQ)

What percentage of my income should disability insurance replace?
Most financial professionals recommend replacing 60% of your pre-tax monthly income. This accounts for the fact that taxes and work-related expenses disappear when you can't work, while your essential living costs continue. If your premiums are paid with after-tax dollars, benefits are tax-free, so 60% replaces most of your take-home pay. High earners or those with significant fixed obligations may want a higher percentage.
Are disability insurance benefits taxable?
It depends on who paid the premiums. If you pay premiums with after-tax dollars, your benefits are generally tax-free. If your employer pays the premiums, your benefits are taxable as ordinary income. This is why the 60% rule works — an employer-paid plan effectively needs a higher gross replacement to net the same amount, while an individually paid plan stretches further.
What is the difference between own-occupation and any-occupation disability insurance?
Own-occupation coverage pays benefits if you cannot perform the material duties of your specific occupation, even if you could earn income in a different field. Any-occupation coverage only pays if you cannot work in any occupation suited to your education and training. Own-occupation is more protective and more expensive — it's essential for specialized professionals like surgeons, dentists, and attorneys whose earning power depends on their specific skills.
How does the elimination period affect my premium?
The elimination period is the waiting time between your disability and the start of benefits — typically 30, 60, or 90 days. Longer elimination periods lower your premium significantly because the insurer carries less short-term risk. Choosing 90 days instead of 30 can reduce your premium by 20–30% or more. Just make sure your emergency fund can cover your expenses during the waiting period.
How does Social Security Disability Insurance (SSDI) work with private disability insurance?
SSDI is a federal program with a strict definition of disability, a 5-month waiting period, and a difficult approval process that can take months or years. After 24 months of benefits you become eligible for Medicare. Private disability policies often offset (reduce) benefits by SSDI amounts, but you should never rely on SSDI alone — many applicants are denied on the first attempt, and the waiting periods leave most people unprotected without private coverage.
How much does disability insurance cost?
Individual disability insurance typically costs about 1% to 3% of your annual income — roughly 0.5%–2% for young, healthy professionals in low-risk occupations. For example, $3,000/month of coverage might cost around $360 per year at the 1% default rate. Your actual premium depends on age, health, occupation class, elimination period, benefit duration, and optional riders. It's a small price for protecting your single largest asset: your earning power.

Important Considerations

⚠️ General Estimate Only: This disability insurance calculator provides a general estimate based on the information you provide. Results are estimates, not quotes — actual coverage and premiums vary by insurer, occupation class, health, age, state laws, and policy terms. It is not a substitute for professional financial advice. Always consult with a licensed insurance professional and financial advisor to determine the appropriate type and amount of coverage for your specific situation.

When purchasing disability insurance, consider factors such as the financial stability of the insurer, the definition of disability, benefit duration, elimination period, riders, and exclusions. Review your coverage periodically — especially after major life events such as a job change, income increase, marriage, or the birth of a child.
